Biologically Protective Optical Cables

YOFC provides optical cables that are resistant to biological hazards caused by rodents, termites and birds, etc. after installation. Optical cables are often damaged by rodents, especially in the southwestern hilly areas, where optical cables in backbone networks are damaged heavily by rodents, resulting in numerous economic losses. Termites not only bite optical cables, but also release formic acid to corrode metal components and sheaths of optical cables. Currently mature methods of protection against biological hazards include physical methods and chemical methods, the former involves...

Optical fibres are housed in a loose tube that is made of high-modulus plastic and filled with tube filling compound. The tube is armored by a layer of glass fibre yarn. Then a LSZH inner sheath and a special nylon outer sheath is extruded. Features • Good mechanical and temperature performances • All-dielectric design, applicable to lightning-prone areas • Small size and light weight • Tube filling compound providing the key protection for fibres • Glass fibre yarns providing certain anti-rodent performance • Nylon outer sheath with high hardness providing certain anti-termite performance...

Single-mode/multimode fibres are housed in a loose tube that is made of high-modulus plastic and filled with tube filling compound. Steel wires is wrapped outside the loose tube. Then a PE inner sheath is extruded and armored with corrugated steel tape. Finally, a PE outer sheath is extruded. Features • Accurate process control ensuring good mechanical and temperature performances • The material of loose tubes with good hydrolysis resistance and relatively high strength • Tube filling compound providing the key protection for fibres • Excellent crush resistance and flexibility • Small size...
